p SPECIFICATION forming part of Letters Patent No. 519,403, dated May 8,1894.

Application filed November 15, 1893. Serial No. 491,019. (No model.) I

To all whom t may concern:

Be it known that I, TONY Lo- GASTO, a citizen of the United States,residing at Marshall, in the county of Harrison and State of Texas, haveinvented a new and useful Axle-Box, of

` which the following is a specification.

My invention relates to improvements in a xle-boxes for vehicle wheelsand to that particular class thereof which is self-lubricatin g, or 1nother words, contains a lubricant-receiving recess from which thelubricant is automatically fed to the spindlev of the axle as necessitymay occasion. Y

The objects of my invention are to produce a very simple construction ofbox that may be easily manufactured and applied, which will ecientlyoperate to discharge or feed the lubricant, and which when in positioncombines with the collar of the axle in such manner as to be rendereddust-proof.

Other Objects and advantages of the inven- I tion will appear in thefollowing description,

and the novel features thereof will be particu larly pointed out in theclaim.

Referring to the drawingsz-Figure l is a perspective view of abearing-box embodying my improvements, the view being from the innerend. Fig. 2 is a longitudinal sectional View, the axle being inposition-within the box. Fig. 3 is a transverse sectional view.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I employ the usual tapered thimble 1, whichis designed to conform to and iit properly upon the spindle 2 of theaxle 3 and to abut againstthe collar 4 usually formed on axles at thejunction of the same with the spindle. `Arranged upon the thimble is thehub-box 3', the same being of a desired contour in section butpreferably tapered to conform to the configuration of the thimble andterminating at its outer end midway the same, where it is reduced andeither permanently secured to or forms a part of said thimble. Thehub-box is of greater diameter than the thimble andk consequentlyproduces an intermediate chamber or recess for the reception of alubricant. The inner end of the box projects beyond the end of thethimble, and is of such a diameter as to t snugly over the collar of theaxle. The thimble has that portion thereof that is covered by the'boxprovided at suitable points with lubricating openings 5. In Operation,previous to the application of the wheel upon the spindle the chamber orrecess between the box and thimble is packed with a suitable lubricatinggrease, and when in position it will be seen that the inner end of thethimble abuts against the collar of the axle,while the inner end of thehub-box snugly encircles and rests upon said collar so that the collaracts to close the entrance to the lubricating recess or chamber andprevents the ingress of dust, grit, and other foreign matter to thelubricating agent and to support the hub box to obviate the necessity ofproviding supports in the lubricating chamber in order to have thelatter unobstructed throughout its entire length. It will be seen thatthe lubricant will remain' in position within the chamber until the heatgenerated by the friction between the thimble and spindle causes saidlubricant to melt, whereupon it will escape through thefeed-perforations in the thimble, gain access to the spindle, and bedistributed thereover. Y

In this manner it will be seen that I have provided a self-lubricatingaxle-box of very simple construction and efficient in operation, theen-ds of the same being closed by the usually employed collar of theaxle so that no auxiliary devices for this purpose of complicatedconstruction are required.

Having described my invention, what I claim is- An axle box comprisingthe tapered thimble conforming to the configuration of the spindle Of anaxle and closely tting the same and adapted to abut against the collarof the axle at the base thereof, and provided at its inner portion Withperforations, and the external encircling box 3 spaced from and forminga lubricant receiving chamber around the inner perforated portion of thethimble, said chamber being unobstructed from end to end and its outerend -being open for the introduction of vthe lubricant, and said boxhaving one end permanently secured to the thimble intermediate of theends thereof, so as to close IOO the lubricant receiving chamber at itsinner In testimony that I claim the foregoing as end, and extendingbeyond the end of the my oWnIhave hereto affixed my signature in thimbleto receive and pass over the collar of the presence of two Witnesses.
